Querying API Calls Within a Period

Updated on 2023-04-06 GMT+08:00

Function

This API is used to query the number of times APIs in an API group are called within a period. The query is based on 1 minute. If the time range is within one hour, the server returns the number of API calls made every minute.

NOTE:

For security purposes, clear your operation records, including but not limited to records in the ~/.bash_history and /var/log/messages directories (if any), after running the curl command on the server to query information.
